登錄Facebook之前iOS 9

我正在使用Xcode 7使用Facebook iOS idk v4.1編寫針對iOS7的應用程序。當我執行Facebook登錄時，FBSDKLoginButton回調中的[FBSDKAccessToken currentAccessToken]仍然爲零。我已經嘗試了幾種SO解決方案來解決這個問題，但迄今爲止還沒有一種解決方案能夠解決此問題登錄Facebook之前iOS 9

我認爲問題出在我的appDelegate。這裏是我的代碼：

- (BOOL) application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation 
{ 
    //for Facebook signin 
    if([[FBSDKApplicationDelegate sharedInstance] application:application openURL:url sourceApplication:sourceApplication annotation:annotation]) 
    { 
     return YES; 
    } 
    //for Google Signin on iOS 8 and earlier 
    else 
    { 
     NSDictionary* options = @{UIApplicationOpenURLOptionsSourceApplicationKey:sourceApplication, UIApplicationOpenURLOptionsAnnotationKey:annotation}; 
     return [self application:application openURL:url options:options]; 
    } 
} 

//iOS 9 and later 
//for Google Signin 
- (BOOL) application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options 
{ 
    if ([[[NSUserDefaults standardUserDefaults] objectForKey:UDLoginType] integerValue] == ltGoogle) 
    { 
     return [[GIDSignIn sharedInstance] handleURL:url sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey] annotation:options[UIApplicationOpenURLOptionsAnnotationKey]]; 
    } 
    else 
    { 
     return YES; 
    } 
}

當我的應用程序從Facebook返回時，應用程序：openURL：options（iOSv9 +）被調用。該方法不包含對Facebook SDK的調用。在應用程序中有一個對Facebook SDK的調用：openURL：sourceApplication：註解（iOSv8-），但我不知道如何將它翻譯爲iOSv9調用，就像Google一樣。據我所知，在Facebook登錄後沒有處理登錄URL。我究竟做錯了什麼？

這裏是你如何能爲iOS 9+

- (BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString*, id> *)options { 
     return [[FBSDKApplicationDelegate sharedInstance] application:app 
                   openURL:url 
                sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey] 
                  annotation:options[UIApplicationOpenURLOptionsAnnotationKey]] 
       || [[GIDSignIn sharedInstance] handleURL:url 
             sourceApplication:options[UIApplicationOpenURLOptionsSourceApplicationKey] 
               annotation:options[UIApplicationOpenURLOptionsSourceApplicationKey]]; 
    }

下面IOS 9

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation 
{ 

     return [[FBSDKApplicationDelegate sharedInstance] application:application 
                  openURL:url 
               sourceApplication:sourceApplication 
                 annotation:annotation 
       ] || 
       [[GIDSignIn sharedInstance] handleURL:url 
              sourceApplication:sourceApplication 
               annotation:annotation]; 
    }
